Anyone succeeded in increasing their Gas mileage? 93 Ranger STX X-tra 4.0 L Auto 2x4

I'm getting around town about 15.5 miles to the gallon.

Has anyone found successful ways to increase their gas mileage?

I saw one post mention the velocity tuner air intake tornado making a dramatic difference. Velocity Tuner -

I've read about adding about 2 ozs of Acetone to each 10 gallons of gas making a dramatic difference.

I can find many claims that these have worked on owner's vehicles and I can find some claims that they didn't work.

It seems it depends on the vehicle and possibly where you live.

Most of these gadgets have money back guarantees, I'm thinking about trying them one at a time and returning them if they don't do anything.

Please only give me replies with experiences with products/modifications.

Thanks

Easiest modification ever!

Drive 10 mph slower than you usually drive. That and do a full tune-up.
